Application led March 28, 1911. Serial N0. 617,339.

To all 'whom t may concern: Be it known that I, JACOB HERMAN, a citizenof the United States, residing at Braddock in the county of Alleghenyand State of Fennsylvania, have invented certain new and usefulImprovements in Cultivat-ors or Harrows, of which the following is aspecication.

This invention relates to improvements in cultivators or harrows, andthe main object of the invention is to provide a harrow that may be usedin connection with a y sulky plow.

l/Vith the above and other objects in view,

I have invented the harrow illustrated iny the accompanying drawings inwhich- Figure 1 is a rear view of my improved hai-row attached to asulky. Fig. 2 is an` g partially in section and partially broken away,

elevational view of my Adevice shown Fig. 3 is a view similarto Fig. 2,of the opposing side of the device, Fig. 32L is a perspective detailedview of a harrow. Fig.

1 indicates an axle upon which are mount.

ed wheels 2 and 3. Mounted upon the aXle adjacent the wheels 2 and 3,are bars 11 and 12 having eyes 13, 14, 15, and 16, through which bars17, 18,-19 and 2O pass. The forward end of these bars are secured to themembers 21 and 21 on the forward ends of the beams 5 and 5, the beam 5being iiXed onto the upper surface of the axle 1, and the beam 5 beingfixed on a plane therewith. The rear portion of these bars support therod 22, `upon which are loosely mounted rotatable members 23, each ofwhich carry a long harrow tooth 24'and a short harrow tooth 25, bothotwhich have their ends bent at right angles, the teeth 25 being on aparallel line directly beneath the teeth 24. Every alternate member 23carries teeth 24 and 25 which are longer than vteeth 24 and 25, making astaggeredl arrangement of these harrow teeth. The

members 23 are cylindrical in shape and are pivotally mounted on the rod22 and have secured to each one thereof a pair ot' teeth, one toothbeing shorter than the other, the short teeth 25 and 25 being directlybelow the long teeth 24 and 24. I The members 23 are independent of oneanother allowing the teeth on one member to rise in dependent oftheother members.

Mounted upon the project-ing ends of the rod 22 is a member 26 part ofwhich runs directly beneath all of the teeth at a pointvery close to therod 22. The ends 27 of this member pass under the rod 22 and bendthere-around and is then doubled upon itself as at 28, and then runsentirely across and above the harrow teeth. Upon the upper portion ofthis member 28 is pivotally mounted an arm 29. Also iXedly on one end ofthe rod 22 is one end of a brace 30, the other end of which is mountedupon the extended port-ion 31 of the aXle 1.

Mounted upon the axle 1 is a frame work 32, upon which is pivotallymounted the mechanism for raising and lowering the harrow teeth.

The mechanism for raising and lowering the harrow teeth may be of anysuitable construction, and, as shown, the sector inember 33 ispivoted-to the frame 32 and is connected by a link 37 to one end of apivotal arm 38, pivoted at 40 on the frame 32 and connected to said armand to one end of an operating lever 42 pivoted at 43 is a link rod 41.By means of lever 42 the sector member 33 may be actuated so as to rockforwardly or rearwardly to cause niember 29 to lower or lift the harrowteeth. Before lever 42 is manipulated, however, it will be necessary torelease the catch 50 formed on lever 34 fulcruined at 40 and connectedby link 48 to a double arm crank 45, which crank ispivoted in a slot 44of lever 42 operated by means of the rod 51, which is linked at one endto crank 45, and is formed with a part 52 engageable with the pin 524carried by lever 42, said part 52 resting on said pin to prevent crank45 moving downwardly. "A handle 55 is formed upon the rod 42, and thishandle will be manipulated so as to draw the crank up, as shown in Fig.5, whereby the inner end of lever 34 will be drawn down and the catch 50drawn up and out of engagement with the sector member 33. It will thusbe seen that the rod 51 'ind the lever 42 will not be actuatedsimultaneously. Vhen it is desired to raise the harrow teeth fromcontact with the ground the lever handle 56 is thrown rearwardly causingthe link 41 to bring the lower end of the link 38 forwardly which drawsthe link 37 forward which in turn swings the bell crank 33 forwardlywhich draws the link 36 and arm 29 upwardly thus raising the member 26and consequently all of the harrow teeth. In order to again lower theteeth to operative position the hook 50 is released from the crank 33 bythe operation of the member 55 whereupon the weight of the teeth willcause them to drop.

Numerous modifications may be resorted to in practice without departingin essence from the details of construction herein disclosed.
